Local structure investigation in ceria-zirconia "k -phase" by XAFS: unraveling the reason for outstanding oxygen storage capacity

open access: yes, 2015
Ceria zirconia solid solutions (CexZryO2, CZ) are well known for buffering oxygen due to fast and easy switch between the oxidation states Ce3+/Ce4+ [1], showing remarkable oxygen storage capacity (OSC), and, thanks to the presence of the zirconium ...

Ceria Zirconia Mixed Oxides Prepared by Hydrothermal Templating Method for the Oxidation of Ethyl Benzene

open access: yesBulletin of Chemical Reaction Engineering & Catalysis, 2013
CeO2–ZrO2 oxides were prepared by the surfactant-templated method using cetyl trimethyl ammonium bromide (CTAB) as template. These were characterized by XRD, FT-IR, TEM, SEM, BET and TPD-CO2.

Study and development of thin films of shape memory ceramics and superelastic zirconia

open access: yes, 2023
reservedShape memory ceramic materials, including zirconia, are a unique class of materials that possess the ability to "remember" their original shape and return to it after being deformed by an external force.
